I have been trying to install MSE for ages and have tried loads of fixes for this error. I have turned Windows Defender off and Windows firewall on.
I'm running Windows 7 Ultimate x64, I have .NET framework 4.5.2 installed and I have never had an antivirus installed on this machine.
On a maybe related matter, I am also having trouble installing two Windows Updates, KB2592687 and KB830477; I don't know if this has anything to do with it.
Please follow the Windows Update Posting Instructions and post the requested data
If the file is too large (8MB compressed), remove the older CBSPersist cab files until the final file is below the limit - you can always post them separately after zipping them. (the forum doesn't allow the upload of bare CAB files, for a number of reasons)
Please also post the C:\Windows\windowsudpate.log file
...also,
Please download and install Malwarebytes Anti-malware (free version) from http://www.malwarebytes.org/products/malwarebytes_free/ - UNtick 'Enable free trial of MBAM Premium' at the end of the installation - and update it, then run a full scan in your main account, and Quick scans in any other user accounts.
Quarantine everything it finds
Ye gods - a 25MB CBSPersist file translates to about 700MB as a CBS log file - no wonder the system was slow !
I did actually say to do a FULL scan with Malwarebytes.
This appears to be the critical error from the WindowsUpdate.log...
The SFC scan appears to be clear of errors, and the CBS.log has no errors in the background.Code:Line 3509: 2015-05-03 14:25:47:050 388 d1c Report REPORT EVENT: {72DC74FE-9BBF-48BA-93D3-6D5BBA14CEFF} 2015-05-03 14:25:46:785+0100 1 182 101 {7E3D95D0-AF45-48FA-917D-8DD9CF4DFF43} 200 80070005 AutomaticUpdates Failure Content Install Installation Failure: Windows failed to install the following update with error 0x80070005: Update for Windows 7 for x64-based Systems (KB2830477).
You haven't posted the CheckSUR.log file - since it doesn't show in the CBS folder, I assume that you haven't yet run SURT/CheckSUR. Please do so, and post the resulting log.
I will post the SURT results tomorrow when I can get round to it. I will leave a full system scan running too and see if it finds anything.
After looking at the error message you posted, I found this guide: https://support.microsoft.com/en-us/kb/968003
However, it didn't help anything as it just said it failed a lot instead of fixing any permissions:
It managed to modify 9800+ permissions, and you say it didn't do anything?
..and the error code that is intended for is a completely different one to the one you are getting!
We are now going to have to start the whole process afresh, since there's no way to tell what's been done (or not done).
PLEASE do NOT go off trying things yourself. Many can do more ham than good - and unless I know what's going on I have no way to know where in the process errors are creeping in.

I'm trying to work on both problems at the same time, as they are probably related - however, the 80070005 error is a lot more generic than that article likes to make out, and can result from file permissions as well as registry permissions, and subinacl isn't really very good with x64 registries anyhow (unless they've updated it lately).
Okay so I have run SURT and it installed successfully, the sfc scan said the same as before and I have attached the CBS + CheckSUR files; here is also a screenshot of the CBS folder now:
